Abstract

A Mössbauer investigation has been carried out on garnets from Měděnec and Ktiš (Czech Republic). Changes of Fe2+ and Fe3+ crystallographic sites were observed in these silicate garnets after temperature processing under oxidising atmosphere. The temperature processes were realised from 200 to 1000°C by 100 degrees. The results of Mössbauer experiments are compared with the results of the chemical analysis, X-ray diffraction, infrared spectroscopy, and magnetic susceptibility measurements.
